摘　　要：文章在传统的平面单极天线结构的基础上,设计了一种采用微带线馈电,在半圆形贴片上开圆形孔的新型平面单极天线,研究了半圆形平面贴片以及接地面的结构对天线性能的影响.研究表明,这种天线能够工作在2—12GHz的频率范围内,并能获得超过140%的工作带宽.Based on conventional structure of the monopole planar antenna, a semicircle monopole planat antenna with a circle-shaped slot is presented in this paper. The proposed antenna is fed by microstrip line , The proposed antenna is fed by microstrip line . Effects of varying the structure of the ground and monopole patch on the antenna performance have been studied. It is shown that the proposed antenna can be operated from 2 to 12 GHz ,bandwidths in excess of 140% can be achieved.
